When the time comes to buy new gear, there is usually a conversation that takes place in my head to help me make a wise decision. It includes the expected questions: Do I need it? Is it good? Can I afford it? Does my son really need food? This is necessary because it is incredibly frustrating to own gear you don’t want to use. If it doesn’t add value, it just sits there collecting dust, mocking you, and basking in your disappointment.
However, there are times when the normal metrics of evaluation fall to the wayside and you are presented with a proposition so tantalizing that you buy with your heart and not your head. One such opportunity may have presented itself in the Sain Sonic 50mm F1.1 lens for $170. Considering other lenses with that kind of aperture are hundreds or thousands more, it seems like a bargain. But how does cost compare to ability? No one expects this to be a top performer, but some examples look nice.
This is a mirrorless lens for APC-S size sensors and it is currently available for Canon EOS M and Sony E-Mount (Not FE Mount) cameras. However, it will be available for the Fuji X mount and Micro 4/3 cameras in the future.

Typically, a lens this fast and affordable isn’t something you buy because it’s the best performer. But that doesn’t mean it can’t be good enough. This lens looks like a lot of fun and at this price point, you should be able to forgive its shortcomings.
Something to keep in mind, however, is that there have been complaints that the aperture width is actually only 40mm which would make it not as fast as advertised (sort of), but beyond that, they don’t really address light transmission so while it may be f/1.1 it may have a T-stop that’s not near that. Again, this really seems like a fun lens anyway.
